Overview

What Privacy Badger does

Privacy Badger is a browser extension created by the Electronic Frontier Foundation that automatically learns to block invisible trackers. Unlike traditional blockers that use filter lists, Privacy Badger learns by watching which domains track you across websites.

What people use it for

  • Blocking third-party trackers that follow users across websites
  • Sending Do Not Track and Global Privacy Control signals
  • Disabling social media tracking widgets like Facebook Like buttons
  • Preventing canvas fingerprinting across websites

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Privacy Badger.

  • It is not an ad blocker; the project states its aim is to prevent non-consensual tracking rather than to block ads
  • There is no Safari build, and Safari on iOS lacks extension capabilities Privacy Badger needs to work
  • Chrome on Android does not support extensions, so Android users have to switch to Firefox or Edge
  • Protection is aimed at third-party trackers and does not comprehensively cover tracking by the site you are actually visiting

Cross-shopped

Softwr does not host reviews and shows no star rating for Privacy Badger, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
